Addition Triangles Math Centers Math Tiles

Description

Give students an addition puzzle with nine connected triangles. They place digits 0–9 at the vertices so the three numbers around each triangle add up to the sum inside it. Each card gives the position of one tile as a starting clue.

Why use Math Tiles?

• Make problem solving hands-on by letting students move number tiles and test their ideas.
• Build flexible thinking as students follow different clues and try more than one strategy.
• Practice perseverance and build confidence by revising a choice when the first idea doesn’t fit.
• Give students meaningful independent practice or have partners explain and compare their thinking.
• Save paper by reusing printed cards and having students record their answers on a separate sheet.

What’s included

• 30 printable addition triangle puzzle cards
• Google Slides version with movable number tiles
• Student recording sheet
• Answer keys
• Teacher setup tips
• Printable 0–9 number tiles

How to use it

Use the puzzles for partner work and ask students to explain how a shared vertex helps them solve the next triangle. For print, cut out the included number tiles or use a set you already have. In Google Slides, students move the tiles in edit mode.
